Chairman Mao once said one is never too old to learn, his words have inspired so many people to study all the time. Life-long learning is very necessary today, many teachers have kept studying for they need to refresh their knowledge. For me, I also like to keep life-long learning, the reasons are in the following.
毛主席曾经说过活到老，学到老，他的这些话鼓励了很多人坚持学习。终身学习在今天是很必要的，很多教师就坚持学习，因为他们需要更新知识。对于我来说，我也喜欢保持终身学习，理由如下。 

On the one hand, the society develops so fast, I don’t want to be kicked out, so I need to keep studying and make myself keep pace with the time. Like the old people, they don’t know how to use computer, some of them learn the computer and some refuse to learn. The result is that the one who doesn’t use computer can’t keep pace with the time. 
一方面，社会发展很快，我不想要被淘汰，因此我需要保持学习，让自己与时俱进。比如老人家，他们不知道如何使用电脑，一些老人家学会了电脑，一些拒绝去学。结果就是不用电脑的人无法与时俱进。 

On the other hand, life-long learning helps me have the passion on life. I am always curious about the new things, so I will want to know them more. If I stop learning, I will stop thinking and feel myself like waiting to die, how terrible it is. 
另一方面，终身学习能让我对生活有激情。我总是对新事物充满好奇，所以我想要了解更多。如果我停止学习，就会停下来思考，感觉自己就像在等死，多么可怕啊。 

Life-long learning is necessary for everyone, it is the only way to make us keep pace with the time. 
终身学习对每个人来说都是必须得，这也是让我们保持与时俱进的唯一方法。
